基于家族优生学的电力系统故障诊断

引入基于家族优生学的进化（FEBE）方法进行电力系统的故障诊断。该方法将正交设计技术引入家庭的子代培养过程，以加强个体的行为改进，避免早熟，加速了进化后期的收敛速度。此方法用于保护和断路器不正常动作或多重故障等复杂情况下的电力系统故障诊断也有满意的效果。算例系统的研究结果证明了FEBE方法的应用提高了电力系统故障诊断的效率和准确率。

Fault Diagnosis in Power Systems Using Family Eugenics Based Evolution Approach

A new family eugenics based evolution(FEBE)theory is presented to estimate the faulty section in power systems. To apply the FEBE method to solving the fault diagnosis problem,an orthogonal design technique is then introduced into the course of offspring's breeding inside a family,so as to enhance the behavior amelioration of individuals against pre-maturity and thus quicken the convergence of the low converging speed in the last period.The method proposed is versatile and can deal with uncertainties in fault section diagnosis of such complicated cases as failure operations of relays and circuit breakers,or multiple faults at the same time.The feasibility and efficiency of the FEBE approach developed for fault-section diagnosis has been verified with the result of a sample power system.
